Full simulation of a building’s HVAC control is important. Good control is the most cost-effective way to reduce plant size and save energy and maintenance cost. To address these issues the control designer needs an easy to use, but accurate tool that simultaneously solves the building thermal, the HVAC system and its control performance. We have developed such a tool. Our new simplified, yet e...

We develop strategies for integrated use of certain well-known variance reduction techniques to estimate a mean response in a finite-horizon simulation experiment. The building blocks for these integrated variance reduction strategies are the techniques of conditional expectation, correlation induction (including antithetic variates and Latin hypercube sampling), and control variates; and all p...

Based on an analysis of the heterogeneous systems for interconnecting distributed infrastructural devices, such as low-bandwidth sensor/actuator-networks and the research prototype experience, the paper describes a productionlevel implementation of an integrating architecture for accessing various infranets via intranets and the Internet as well as telecommunication networks. Its modularity all...

In the past years, buildings are designed to be more and more powerful and intelligent mechanism. But it is still far from being perfect since building systems are in lack of a uniform specification to establish standards for various appliances and communication protocol, and are also in lack of a robust kernel to integrate all sub-systems in the buildings. For the former problem, we expect tha...
